Breaking the chains: hot super-Earth systems from migration and disruption of compact resonant chains
Abstract 'Hot super-Earths'(or 'mini-Neptunes') between one and four times Earth's size with
period shorter than 100 d orbit 30–50 per cent of Sun-like stars. Their orbital configuration …

Formation of planetary systems by pebble accretion and migration-Hot super-Earth systems from breaking compact resonant chains
At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii
and orbital periods of less than 100 days. We use N-body simulations including a model for …

Overstable librations can account for the paucity of mean motion resonances among exoplanet pairs
P Goldreich, HE Schlichting - The Astronomical Journal, 2014 - iopscience.iop.org
We assess the multi-planet systems discovered by the Kepler satellite in terms of current
ideas about orbital migration and eccentricity damping due to planet–disk interactions. Our …

Convergent migration renders TRAPPIST-1 long-lived
TRAPPIST-1 is a late M-dwarf orbited by seven Earth-sized planets with orbital period ratios
near a chain of mean motion resonances. Due to uncertain system parameters, most orbital …

A reassessment of the in situ formation of close-in super-Earths
Context. A large fraction of stars host one or multiple close-in super-Earth planets. There is
an active debate about whether these planets formed in situ or at greater distances from the …

Mean motion resonance capture in the context of type I migration
K Kajtazi, AC Petit, A Johansen - Astronomy & Astrophysics, 2023 - aanda.org
Capture into mean motion resonance (MMR) is an important dynamical mechanism because
it shapes the final architecture of a planetary system. We simulate systems of two or three …
